Abstract
The invention discloses a composite weed killer with pyridaben. The composite weed killer comprises two main effective ingredients being pyridabe and daidzein, wherein the weight part ratio of the pyridabe to the daidzein is 8:1-7:1. It is found that the pyridabe and the daidzein have the quite good synergetic weeding effect due to compatibility at the specific ratio, and the synergetic effect is quite obvious particularly when the weight part ratio of the pyridabe to the daidzein is 8:1-7:1.
Description
Technical field
The present invention relates to a kind of herbicide, specifically a kind of compound herbicide containing pyridaben, belong to agricultural technology neck
Domain.
Background technology
Herbicide (herbicide) is referred to can make weeds that withered medicament thoroughly or selectively occurs, also known as herbicide,
To the class material for eliminating or suppressing plant growth.Sodium chlorate therein, borax, arsenate, trichloroacetic acid are for any kind
The plant of class plays the role of withered, and its effect is affected by herbicide, plant and the factor of environmental condition three.It is divided into by effect and goes out
Natural disposition and selective herbicide, selective herbicide is particularly nitrophenol, chlorophenol, carbamic derivative majority to be had
Effect.World Herbicide development is gradually steady, main development efficiently, low toxicity, wide spectrum, the kind of low consumption, environmental pollution is little
Disposable treatment agent is increasingly becoming main flow,
Pyridaben is wide spectrum, contact acaricide, can be used to prevent and treat various food vegetalitas evil mites.It is to the whole growth period of mite
Ovum, young mite, deutonymph and there is good effect into mite, equally have the effect of killing of obvious speed into mite to the mobile phase.Dai is (big
Beans glucoside unit) No. CAS:486-66-8, belongs to one kind of flavone compound isoflavones, and is classified as the one of phytoestrogen
Kind, this is a kind of non-steroidal compounds with similar estrogen function extracted from plant.
Applicants experimentally found that its pyridaben is with Dai, and the compatibility under certain proportion is particularly pernicious for weeds
Grassy weed has good preventive effect.
The content of the invention
For the problem that above-mentioned prior art is present, the present invention provides a kind of compound herbicide containing pyridaben, mite of rattling away
Ketone is obvious in a certain proportion of Herbicidal synergic with Dai.
To achieve these goals, the technical solution used in the present invention is：One kind includes two kinds of principle active components：Rattle away mite
Ketone and Dai.
Described pyridaben is with the ratio of the parts by weight of Dai, 8:1-7:1.
Described pyridaben accounts for the 1-30% of herbicide gross weight with the weight sum of Dai.
The present invention under specific ratio by pyridaben and Dai compatibility by having found there is good Synergistic herbicidal
Effect, the particularly ratio in pyridaben and the parts by weight of Dai are 8:1-7:Between 1, its synergy is apparent,
Whole reagent cost is relatively low, and toxicity is less.

Toxicity Determination is tested
Test method：Test soil is quantitatively filled at the 4/5 of basin alms bowl, water is poured from top makes soil complete wetting to saturation
State, soil surface is uniformly sowed at by pretreatment for examination weed seed (barnyard grass), and earthing 0.5cm after planting moves into greenhouse routine
Culture, with the bottom infiltrating irrigation mode moisturizing of basin alms bowl to saturated mode；Weeds emerge laggard seedling singling in the ranks, it is ensured that the density one of weeds
Cause；Dispenser process is carried out to the 2-3 leaf phases to weeds length, each processes 4 repetitions, calculate preventive effect, then use least square method meter
Concentration EC50 (95% confidential interval) in suppressing is calculated, then co-toxicity coefficient (CTC) is calculated with the abundant methods of Sun Yun：
Actual measurement toxicity index (ATI)=(standard agent EC50/ reagent agents EC50) × 100
Theoretical toxicity index (TTI)=(percentage composition of A in the toxicity index × mixture of A)+(B in the toxicity index × mixture of B
Percentage composition)
Co-toxicity coefficient (CTC)=[mixture actual measurement virulence coefficient (ATI)/mixture theory virulence coefficient (TTI)] × 100
Co-toxicity coefficient (CTC) >=120 shows as synergistic effect；Co-toxicity coefficient (CTC)≤80 shows as antagonism；80<It is malicious altogether
Coefficient (CTC)<120 show as summation action.
Testing result is shown in Table 1.
Synergy of the Herbicidal combinations of the present invention of table 1 to barnyard grass is determined：
A is pyridaben in table, and B is Dai.
| Reagent treatment | ATI | TTI | Co-toxicity coefficient CTC |
| A：B(20：1) | 42.2 | 36.7 | 114.9 |
| A：B(12：1) | 36.7 | 31.1 | 118.1 |
| A：B(8：1) | 66.7 | 30.9 | 215.9 |
| A：B(7：1) | 58.6 | 28.5 | 205.6 |
| A：B(5：1) | 30.2 | 27.9 | 108.2 |
| A：B(1：1) | 26.3 | 25.1 | 104.8 |
| A：B(1：2) | 23.2 | 21.3 | 108.9 |
| A：B(1：7) | 21.2 | 19.3 | 109.8 |
From the measurement result of table 1, when the proportioning of pyridaben and Dai is 8:1-7:When between 1, co-toxicity coefficient is all higher than
120, particularly 8:When 1, with obvious synergistic effect.
Field control effectiveness test
The field efficacy contrast test in rice field is carried out with various embodiments of the present invention, spraying treatment is carried out, dosage is 20a.i.g/
Hm2,30d counts respectively the preventive effect to barnyard grass after medicine, the results are shown in Table 2.
The herbicide of the present invention of table 2 is contrasted with single dose herbicide preventive effect,
From the field control effectiveness test of table 2, in herbicide effective ingredient consumption of the present invention (Herbicidal combinations i.e. of the present invention
Consumption) as single amount of application on the premise of, barnyard grass preventive effect is significantly improved, this is consistent with Toxicity Determination result of the test,
With obvious synergistic effect, it is not pyridaben with the proportioning of Dai 8 to carry:1-7:When between 1, barnyard grass preventive effect is significantly carried
It is high.The rice is doing well, and survival rate is normal.
The explanation of above example is only intended to help and understands the method for the present invention and its core concept.It should be pointed out that right
For those skilled in the art, under the premise without departing from the principles of the invention, the present invention can also be carried out
Some improvement and modification, these are improved and modification is also fallen in the protection domain of the claims in the present invention.
